    Too windy for scope?

    Advice appreciated. In open wind prone wetland, winds of 8 mph gusting to 18mph - I’ve got an 88mm scope with a benro Mach 3 tripod. Would one expect a lot of wind vibration in that setup or should it be ok?` Thanks, Jeff

    leveling head for tripod with scope?

    spotting scope and bicycling on rough paths?

    Hi, thinking of getting a spotting scope, which I'd get around in a pannier on a bicycle often traveling really bad paths (forest service roads, old logging roads, canal towpaths). my thought was to cushion the scope in the pannier with some foam, but realizing they're precision instruments...

    Nyack Harness Review (and Kowa Genesis 8.5x44 impressions)

    When I got my gnu, bigger, Kowa Genesis 8.5x44 binoculars, I decided to also replace the harnesses I’d been using with my (somewhat) lighter 8x32 Nikon premiers for the last 20 years. Replace and upgrade – the made in Montana Nyack harness is the best I’ve ever used. The straps at 1.5 inches...

    what do astigmatism and coma look like in real use?

    hi, I've read the explanations of those terms in the review glossaries, and I think I can understand what the views would be in a controlled testing room for binoculars that rate high for those parameters. but in real use, looking at birds in forests and wetlands, what losses are there in what...

    my backyard is the forests and creeks of rock creek park, and I hear there are a lot of birds there, but it's often mostly hearing not seeing because in this season where there are trees there are leaves and the birds seem to be behind the leaves. so even if I can't see them I do get great...
